Vintage Hand-cut crystal champagne coups set of 4, elegant fine dining barware,

...housewarming gift to the couple A set of 4 hand cut crystal champagne coupes - there are a few slight differences between the glasses, on the foot (one being a bit smaller / higher) and the height of the glasses (1 being a bit taller than the other 3) ands the thickness of the glass (1 being a bit thicker). This could all be attributed to these being hand made pieces in the same line, but not necessarily from the same production run. Only 1 is labelled: "Ha. Ka. Echt Bleikristall handgeschliffen" (Ha. Ka. being the maker possibly Hauck & Kabsch, Real Lead Crystal, hand cut). Hauck & Kabsch was a German glass manufacturer founded in 1856, known for producing high-quality glassware, particularly in the fields of scientific and medical instruments, and later, decorative glass. Condition: with small marks or age and use, including a few tiny fleabites to the top rims Size: 4 3/4 inches tall (4 7/8" on the tallest one), the tops are 4 1/2 - 4 5/8" diameter
